I was referred here from an Office 365 post. This is my original issue:
I recently enforced a password policy for the first time. I am using Microsoft Server 2012 and syncing my AD to Exchange Online. After a user changes their windows password via Ctrl, Alt, Delete, Outlook will not prompt for new credentials. The old credentials continue to work. However, if the user logs on to OWA, the old password does not work, and the new one does.
I have the FIM configured to sync every hour, and I have tried manually syncing it as well. Restarting the computer does not cause Outlook to prompt for the new password either. It takes about a day for Outlook to catch up.
How can I get Outlook to prompt for the new password right after the user changes their windows password?
